/JZJ/Zjy Witnesses Inventor ttorney stance, the springa'rm 2 is shown as being;

connected` with, the lowerV part-23 of the vehicle spring 11. A clamp of any desired sort may be utilized for connecting v,the freeA end of the spring arm 2 with the lower part 23.0f1the vehicle spring 11. In the present` instance, although not necessarily, this clamp consists of upper and lower members ,f 24 ,and 25, respectively, the member 24 eX-y tending across the top yof the part 23, downwardly across the'rear edge of the part23, and partway across the bottom of the ele? ment23, as clearly shown i'n Fig. 2.l The and 25 terminate in mating flanges 28,A

through which may be passed a pivot bolt 29, receiving pivotally, the free end of the spring arm 2.

yInpractical operation, the ribs 9 ,ofthe heads 3 are normally spacedfapart, as clearly a shownin Fig.,1the ribs `9 beingfconsidered as parts of the'end faces 4.". Owing to the fact that the'ends 9 are spaced apart, the

vehicle'spring 11 may yield, under normal conditions, without bringingthe ribs 9 into engagement .uponeither iside of the `pi-vot element `8. Vhen, however, the vehicle springgll is compressed unduly', the ribs 9 willk come into contact uponhthe righthand side of the pivot lelement'S, in; Fig. -1, ,the spring arms `1 and 2 beingthereupon put under tension. When the parts 10 and 28 of the vehicle spring, 11 are separated sud# denly, as frequently happens, after :an undue compression, the ribs 9 come Vinto Contact upont'he left` hand vside of'the pivot element 8 Vin IFig. 1, thereby putting thesprin'g arms 1 yand 2 under tension. Thusthe shock lab,-k sorber will be rendered effective to relieve undue tensionupon the vehiclesprin'g,'11,v

whether such tensionresults from an. undue compression of the vehiclespring, or an undue expansion.v of the vehicle spring.` However, owingto the fact that the ribs 9 are normally spacedapart, under ordinary Vworking vconditions of t-he vehicle springl 11,r the shock absorberwill not be underv tension continually.

.In .order that thel ribs 9 may be lspaced apart under workingconditionman adjust ment must be effected between the yspring,

arms 1 `and v2. This `adjustment may be brought about by loosening the wing nut 21 and bysrotating the secondary` disk l19.with

respect to the primary disk 12,1 the -interfitting ribsl 20 serving to hold the disks inv their adjusted positions.y

Having thusfdescribed the invent-ion,`vwhat is claimed is;- n j 1. A1 shock absorber comprisingl spring arms having spaced end faces yadapted to come into contacty at :both extremities g means for pivotally connecting lthe arms inattaching means upon'the free endfof one arm; amovable member pivoted to the free end'of the other arm; attachingmeans s up. 'porting the movable memberv for pivotal movement whereby when the movable mem ber is operated, the space between the eX- termediate the extremities of the end faces L tremities of the end faces `may be adjusted;

" and mechanism` fory holding themovable v member against movement, thereby to retain the extremities of the end faces'offthe spring f ik arms in adjusted relation. .l

2. A shock absorber comprising spring` arms having enlarged end faces adapted to come into contact successively at both eX-` tremities; means for pivot-ally connecting the arms intermediate the extremities of the end faces; means for attachingthe free end i 0f `one arm to a vehicle spring; a primary disk eccentrically pivoted to the free end of theot-her arm; a secondary disk; means for j Y securing thesecondaryk disk toa vehicle spring; a clamp connecting the disks; and

i1i.terengaging elements 'upon the adjacent faces of the disks.

In testimony that I claim the foregoing' as my own, I have hereto afliXed my signature in the presence of two witnesses.
